Le ters Patent No. 101,445, dated Apr-i1 5, 1870.

IMFROVBMER'I. IN EYDRAULIC ENGINES.

The.8chodu1o referred to in these Letters Patent and making part 0': thesame.

To all whom it may concern:

Be it known that we, WILLIAM EATON, Bnmw Amswon'rn, and GEORGE W.Soo'r'r, of Blackstone, iii the county oi- Worcester and State ofMassachlb setts, have invented a new' and improved Machine forForcingand Spreading Liquids; and we do hereby declare that the following is afull, clear, and exact description thereof, whiclnwill enable othersskilled in the art to make and use the same, reference being bad to theaccompanying drawing forming part, of this specification, iii which- Thedrawingrepresents a sectional view of out improved machine for forcingand spreading liquids.

This invention relates. to machinery employed to sprinkle oil upon woolto prepare it or the cards and consists in animproved combination ofparts which will be specified hereinafter.

The invention consists, first, in the application of .an automaticregulator to the apparatus for forcing the liquid.

In the drawing- A. represents the reservoir of the liquids connected bya pipe, B, with a pump, 0, of suitable kinds.

The pump draws the liquid from the reservoir and forces it through apipe, D.

The pipe D is bent so that it will arrive at a point higher than thelevel of the liquid in the reservoir.

The end of the pipe 'D is contracted or divided to throw the liquid in afine spray or stream.

At a point higher than the level of the liquid in A, is arranged in' thepipe D,-a valve, a, which does not obstruct the passage of the liquid inD, but closes the connection between the pipe D and a branch, E, whichleads to the upper part of the reservoir. The valve is suspended frohn,or rather held down by a weighted lever,-F, as shown.

When the force of the pump exceeds the capacity or the so that theliquid will be compressed in the pipe D, the valve is by such forceelevated, and thesurplus liquid is allowed to pass through the pipe E,back into the reservoir. r

The degree of pressure can be regulated'by adjusting the weight on' thelever F.

Where expensive oil or other valuable liquid is" to be thrown in certainquantities against loose wool or other objects, the perfect controlgiven by the valve on is of great service on account of the greatereconomy and exactness obtained by the same.

A spray-nozzle, G, is employedon the end of the pipe D for'the purposeof spreading the'liquid.

The nozzle has a tapering central bore, 1), smallest near the outer end,and an enlarged. chamber, 0, at the lower end.

In this chamber is arranged a line sieve, d, which serves to arrest allimpurities that may be contained in the liquid.

Near the outer end the bore b is quite small and ends in one or moredischarge apertures. In escaping through these the liquid formerlycompressed will suddenly expand, and, mixing. with the air, it willproduce a very fine spray which will, spread over a considerable space.

Having thus described our invention.

We claim as new and desire to secure by Letters Patent- The combinationof oil-reservoir A, pipe B, pump 0, pipe D D D, weighted valve a. ll,return-pipe E, and spray-nozzle G, all said parts'being constructed andarranged as set forth and for the purpose specified.
